R1637? 2' were a LINK FOR CHAIN AND DETACHABLE HINGES FOR J3EE SAME.

Application filed June 27,

To all whom it may concern I Be it known that l, BERNARD llLlnsTnKiN, acitizen of the United States of America, and a resident of l vashington,District of Columbia, have invented a new and useful Improvement inLinks for Chain Bracelets and Detachable Hinges for the Same, of whichthe following is a specification.

lhen carrying bracelets in stock a large number is required to meet allthe demandsas to size. To a great extent this may be avoided in the socalled chain bracelet by preparing detachable links ready for assemblyto build up a braclet of any desired size. One object of my invention isto make such a detachable bracelet link. .nnother object of my inventionis to provide a bracelet link vith. a. detachable hinge of strong anddurable construction without sacrificing the beauty of the assembledbracelet. Another] object of my invention is. to make such a hinge notonly easy and quick for assembly but to also provide means for detachingany link without the intervention of a skilled mechanic. Another objectof the invention is to make a bracelet link and a hinge therefor in sucha manner as to build up a chain bracelet without the necessity ofswaging the hingepivots.

in the drawing which forms a part of my specification Figure 1 shows aperspection view of several links connected.

tel'erring in detail to the drawing: 1 represents a link made up ofwalls of any de- 1922. SeriaI No. 571,311

- sirable thickness and from any metal such as silver, gold or platinumhaving a pro vision generally indicated 2 for a gem or gems on the topwall. The bottom wall, three being left open and the edges made smoothsince the said edges come into con tact with the .skin.

In the form shown in Figures 2, 3 and 5, each link is provided with ahinge pin, 1:, at

one of the end faces and a socket, 5, at the opposite end face. The endfaces are beveled oii' from midway toward the lower face of the link asshown at 6, so as to permit the assembled bracelet to ties into anannulus. The hinge pin is best shown in Figure 6. It consists of a pieceof halfround rod bent into U shape with the flat faces of the half.

round rod facing each other clearly shown 1n the drawing. The arm 11',of the hinge pin differs from the companion arm 12, in

that it has a shoulder, 9 at the free end there of. The arm 12 ispermanently attached to the end face of the link by soldering or it maybe made integral with the end face. 'he webb 8, of the li-shaped hingepin is slightly springy even after. it has been heated, so that thetendency for the two arms 11 and 12 is to stay slightly spread apart asshown in Figure 6.

The socket is formed by soldering on the inside of the end face, of thelink, a piece of tubing, 1 1-, with a portion cut away along a chord.The inner diameter of the tubing being slightly larger than the diameterof the pin Of the two faces 16 and 17 one face is formed with a socketopei'iing as shown at 18 (Figure ,9) the opposite fare being leftclosed. The socket opening 18, is formed in sliding lit with the hingepin so that there is formed a retaining shoulder 15 which cooperateswith the shoulder 9 on the hinge pin. A small hole, 20, is also providedin the socket tubing as seen in Figure a. l l hen assembling one link toanother the two links are placed so that the end 8 of the hingeregisters with the socket opening 18 of the other link. The pin is thenslid endwise into the socket the prong 11 approaching 12 until theshoulder 9 reaches beneath the inside of side face 16 when it snaps outdue to the slight springiness of the web 8, the parts assuming therelative positions illustrated in Fig. 11 and thus forming a safe andstrong catch.

7 pointed tool can be used'for one or the other ofthe prongs 11 or 11?as I provide each of the socket tubes with a hole 20.

The pins shown at Figures 8 and 10 differ by a slight change and one orthe other -may be used for mere mechanical convenience.

I claim: 1. A1cha1n link for a bracelet compr1s1ng a socket adapted toreceive a hinge Ipin, a. split hinge pm to fit said socket, said socketbeing contained in theend face 'ofthe. link, a longitudinalslot inthe'face of the link communicatingwith said socket and complementary detentson the hingepin and socket;

' 3; A hinge pin for" chain link-bracelets having two-prongs and amiddle body, said prongs being vyi'eldingly held at a space from .thesaid middle body, and locking shoulders on said rongs. g I

4:; A clam" for a bracelet having a socket along its end face, alongitudinal slot com- The hinge- Laauaso municating with said, socket,a perforation in the wall of said socket opposite the slot and a pinretaining shoulder in said socket.

5. A chain link for 'a bracelet having a longitudinal slot ingits endface, a socket communicating with said slot, a retaining shoulder at oneend of said socket and a hole in the wall of said. socket opposite theslot and near the retainingshoulder, a yielding split hinge pin to fitinto said socket and to be retained by saidjshoulder.

'6. A chain link for a bracelet having a socket ad acent its end face,alongitudinal slot comiininieating with said socket through the I endface a retaining shoulder in said socket, a hinge pin to disconnectedlyfit into said socket and means permitting the "removal of said hingepin. p

' 79A chain link for a bracelet having a socket adjacent its end face, alongitudinal slot communicating through the "end face to the socket, aretaining shoulder. in said socket, a split pint'o disconnectedly entersaidsocket, a shoulder on said pin to co operate with the shoulder inthe socket-and meansfacilitating the disconnec'tion of said pin from thesocket.

' 8. A chain link for a bracelet and hinge thereof comprising abox likebody and a hinge socket at theendface thereof,'a split hinge pin anddetachable locking means be tween the socket and pin.

. 9. A hinge for two bracelet links to be hinged side by side,comprising a socket communicating with afa'ce of a link and a splithinge adapted to be detachably locked in saidsocket.
